What is a Dissecting microscope or a Stereo microscope? A dissecting microscope—also known as a stereo microscope—is an optical microscope study apparatus that enables the observation of an object at low to moderate magnification (typically 5x to 250x) through reflective light versus transmitted light. Thus, it’s a microscope made for viewing little details that could … Read more
Designed to enlarge things too tiny for the human eye to see, a microscope is a tool. It provides a portal to the hidden world of minute structures, allowing medical practitioners, teachers, and researchers to examine materials, cells, and creatures in until unheard-of clarity. Microscopes range significantly in kind, from simple to very sophisticated models. … Read more
What is Trinocular Microscope? Principle of Trinocular Microscope A trinocular microscope is similar to a binocular microscope but has an additional third eyepiece for a camera. It shines an LED light on the specimen and projects it onto a computer screen through a digital camera. The trinocular microscope is essentially a binocular microscope that focuses … Read more
An electron microscope is an instrument which produces an image of a sample by means of a beam of electrons. Optical microscopes use light to form an image, electron microscopes have greater resolution, and can be used to observe objects that are too small to be seen with an optical microscope. In a large variety … Read more
What is cryo-EM? Principle of cryo EM Types of cryo EM Cryo-electron microscopy (cryo-EM) is a collection of special methods. These are broadly categorized into two types, mainly cryo-transmission electron microscopy (cryo-TEM) and cryo-scanning electron microscopy (cryo-SEM). Each has its own advantage in the analysis of biological samples in their native state, frozen by cryo-preparation. … Read more
Epi-Fluorescence Microscopy is defined as an optical imaging method, which is employed in laboratories for visualization of fluorescent-labeled samples. The technique is widely described as an essential approach, and it has been repeatedly applied in cell studies, tissue examinations, and even in material analysis. In this method, illumination is delivered from the same side / … Read more
What is Working Distance? Working distance is defined as the distance that is maintained between the “objective lens” and the specimen, during focusing; it is measured along the optical axis of the microscope. It is considered critical, because it determines the space available for manipulating the specimen, adding reagents, or using tools; a short working … Read more
A compound microscope is a laboratory instrument with high magnification power, which is consists of more than one lenses.
